Edgewise outliers of network indexed signals
Christopher Rieser, Anne Ruiz-Gazen, Christine Thomas-Agnan
We consider models for network indexed multivariate data involving a dependence between variables as well as across graph nodes. In the framework of these models, we focus on outli…
Extending compositional data analysis from a graph signal processing perspective
Christopher Rieser, Peter Filzmoser
Traditional methods for the analysis of compositional data consider the log-ratios between all different pairs of variables with equal weight, typically in the form of aggregated c…
A method to identify geochemical mineralization on linear transect
Dominika Mikšová, Christopher Rieser, Peter Filzmoser +2
Mineral exploration in biogeochemistry is related to the detection of anomalies in soil, which is driven by many factors and thus a complex problem. Mikšová, Rieser, and Filzmoser…
Identification of mineralization in geochemistry along a transect based on the spatial curvature of log-ratios
Dominika Mikšová, Christopher Rieser, Peter Filzmoser
Detecting subcropping mineralizations but also deeply buried mineralizations is one important goal in geochemical exploration. The identification of useful indicators for mineraliz…
